Don't let my big d**K scare you, I'm really just a nice guy  
 
Almost got into an accident when I saw that one.  Not so much because it is that funny, but because someone actually drives around with that on thier car.

If you're going to ride my ass, at least pull my hair

Another Capitalism Success Story

What would Scooby Doo?

T*ts on a Ritz, um,um, good cracker. Seen on a 63 Rambler with an 80 year old couple who looked like they where on their way to church. I laughed so hard that I almost had to pull over.

Not a great bumpersticker but, rather, my all-time favorite juxtaposition, was the guy I saw with a No Jap crap for this American sticker proudly displayed on the spare-tire cover of his...Suzuki Samurai!  I don't know if the placement was a brilliantly subtle & ironic mockery of the mindset behind the sticker or a case of complete idiocy, but it's stuck in my mind for over a decade now.

Well Peter, I have one in the same vein as yours; one I have remembered for years.
 
I'm traveling on the freeway one day and I spy a car with a bumper sticker that says  Member Mensa Society. So I think, I gotta catch up to see what the really smart person looks like. I catch up, look over, and here's this guy smoking the hell out of a cigarette with all the windows up. As I let off the gas, all I can think of is, how smart do you have to be to consume something that will kill you.
 
My apologies to all you smokers out there.

I had a guy in a Toyota minivan flip me off and yell at me about my riding a Jap bike (my KLR was built in Thailand, just for the record) at a light just before he turned off into a Walmart.  The rear of his van was covered in Buy American stickers...    I didn't see if there was a MENSA sticker or not...
